.To all whom it Amay concern.- I

Be it known that I, Louis MARKS, of the city and county. of San Francisco, State of California, have invented an Improvement in Carburetors;4 and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improvements 1n hydrocarbon-gas generators. It

consists of a series of superposed shallow pans or chambers fitted within an interior containing-tank, with means for supplying the 'cham bers with the hydrocarbon liquid, and a peculiar arrangement of perforated pipes and chambers through which the air is forced for the purpose of enriching it toform a gas, and in certain details of construction, all of which will be more fully explained by reference to the accompanying drawings, in which- Figure I is a vertical section taken through the exterior chamber and the interior superposed vessels. Fig. 2 is'a horizontal section showing one of the interior chambers.

A is the exterior tank, and B, C, and D are shallow vessels of different diameters, the largest standing nearest the bottoni of the exterior tank, the next supported above this be ing of smaller diameter, and so on for as many as it may be desired to employ.

The top of the tank has a closed cover, through which passes a pipe, E, and a supply of hydrocarbon liquid is delivered through this into the upper vessel, D, and by means of overflow-pipes F each of the vessels below is supplied with the liquid. Exterior gages, O, are connected with the vessels and show the amount in each. In the center of each of these vessels is a close cylindrical chamber,

G, into which air is delivered through pipes H, these pipes being supplied from a main, I, which receives the air fromthe pump or forcing apparatus. Each of the pipes H is pro- A vided with a cock or valve, so that the air ence of the pans or vessels B, C, and D, are

tubes or cylinders J, made of perforated or gauze material, and these cylinders are united by pipes 'K, of the same material, extending from one toA another all about the circle. These pipes are'coveredwith cotton wicking, felt, or other porous material, which is wound around them and also around the verticalcylinders J, andthe latter are also filled with sponge or other porous material. Around the whole of these and upon the top are placed disks of felt P, or other suitable porous material, the object of all this being to cause the air to filtrate slowly through the material and the hydrocarbon liquid which is saturated,

and thus combine with the air a sufficient por-A through the pipe L into the perforated cylin-- der J, with which it connects,-and from this cylinder it` will pass successively through the connecting-pipes K, from one of the cylinders J to the next, thus becoming thoroughly saturated and impregnated with the vapor' or gas. rapidly through the pipes K, and thus pass around the circuit faster than isv desirable, I so arrange these pipes K that the entering end of one stands in a different plane from the departing end-of the next one, which is connected with the same cylinder J. thoroughly impregnated gradually escapes through the porous material and passes upward to thetop of the tank A,escaping through 'the discharge-pipe M and being led to the gasometer or recei-ver. 'N is a discharge-pipe, through which the heavy liquid is drawn oi as it becomes too poor to supply hydrocarbon to the air.

Having thus described my invention, what I claim as new, and desire to secure'by Letters Patent, is- '1. In a carbureting apparatus, the combination of a hydrocarbon-'gasgenerator, consisting of an exterior tank, the interior-,superposed shallow vessels `of decreasing diameter from the bottom upward, a supply-pipe,

In order to prevent the air iiowing too Y The air'becoming overflow-pipes in each vessel, an internal chamber Within the vessels containing air under pressure, and the perforated dischargepipes uniting said chambers and provided with a porous or fibrous covering, substan- Y tially as described.

` pipes by which they are connected, said cylinders and pipes being inclosed in fibrous or porous material and ,receiving air from the central chamber, substantially as herein described.

3. In a carbureting apparatus, the vessels or pans for containing the hydrocarbon placed in a series within an exterior inclosing-tank, having the central chambers receiving air under pressure, a series of vertical cylinders or chambers surrounding the central one and having an interior packing of sponge or porous material, and pipes by which they are united, said pipes having the receiving and discharge ends in different planes and covered with brous or porous material, substantially as herein described.

4. In a carbureting;r apparatus, the superposed hydrocarbon-containing pans within an outer inclosing-tank, the central air-chamber and the su rrounding perforated-cylinders, one of which is connected with the central airchamber, while the others are connected with the first and each other successively by intermediate perforated pipes, the same being covered with brous or porous material, and the fibrous or porous disks coveringand surrounding the same, substantially as herein described.

In Witness whereof I have hereunto set my hand.
